Fuzzy PID control method for damping of electronically controlled air suspension shock absorbers for vehicles

Abstract A damping fuzzy proportional-integral-derivative (PID) control method for electronically controlled air suspension shock absorbers was proposed to reduce the RMS values of body vibration acceleration and improve vehicle ride comfort. Depending on operating mode absorber, a mechanical model absorber established. PID technology is designed by combining algorithm with concept. The adaptive expansion factor cybernetics domain controller calculated considering nonlinear characteristics time delay controller’s adaptability. Then, parameters are adjusted based deviation rate parameters. detection platform produced an enterprise selected build experimental environment analysis. Simulation results reveal that when speed 30 km h −1 , upon applying approximately 0.02 0.05 −2 respectively, Class B C road surfaces. Furthermore, using has little fluctuation; 60 0.022 0.028 surfaces, indicating can effectively rider
